Chrysanthemum plant named `Pink Papillon`

ABSTRACT

A Chrysanthemum plant named Pink Papillon particularly characterized by its flat capitulum form; flat capitulum form; daisy capitulum type; light pink ray floret color; diameter across face of capitulum of 35 to 37 mm when fully opened, when grown as a pinched spray pot mum; very floriferous, with an excellent display or many small flowers; photoperiodic flowering response to short days of 52 to 62 days; plant height, with 14 long days after sticking unrooted cuttings and with 1 to 2 applications of 2500 ppm B-9 SP, ranges from 20 to 28 cm when grown as a pinched pot mum with 4 cuttings in a 15 cm pot; branching pattern is spreading and very prolific, with each plant developing 6 to 8 laterals after pinch; and recommended as a spray pot mum.

The present invention comprises a new and distinct cultivar of Chrysanthemum, botanically known as Dendranthema grandiflora, and referred to by the cultivar name Pink Papillion.

Pink Papillon, identified as 6969 (93-#02154) is a spontaneous mutation of the cultivar Papillon, disclosed in U.S. Pat. No. P.P. 7,435, and was selected to expand the color range of the parental variety.

Pink Papillon was discovered and selected under the directive of Cornelis P. VandenBerg as one flowering plant within a flowering block of Papillon in October of 1992, in a controlled environment in Pendleton, S.C.

The first act of asexual reproduction of Pink Papillon was accomplished when vegetative cuttings were taken from the initial selection in January of 1993 in a controlled environment in Pendleton, S.C., by technicians working under the directive of Cornelis P. VandenBerg.

Horticultural examination of controlled flowerings of successive plantings has shown that the unique combination of characteristics as herein disclosed for Pink Papillon are firmly fixed and are retained through successive generations of asexual reproduction.

Pink Papillon has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity and daylength, without, however, any variance in genotype.

The following observations, measurements and comparisions describe plants grown in Salinas, Calif. and Leamington, Canada, under greenhouse conditions which approximate those generally used in commercial greenhouse practice.

The following traits have been repeatedly observed and are determined to be basic characteristics of Pink Papillon, which, in combination, distinguish this Chrysanthemum as a new and distinct cultivar:

1. Flat capitulum form.

2. Daisy capitulum type.

3. Light pink ray floret color.

4. Diameter across face of capitulum of 35 to 37 mm when fully opened, when grown as a pinched spray pot mum.

5. Very floriferous, with an excellent display or many small flowers.

6. Photoperiodic flowering response to short days of 52 to 62 days.

7. Plant height, with 14 long days after sticking unrooted cuttings and with 1 to 2 applications of 2500 ppm B-9 SP, ranges from 20 to 28 cm when grown as a pinched pot mum with 4 cuttings in a 15 cm pot.

8. Branching pattern is spreading and very prolific, with each plant developing 6 to 8 laterals after pinch.

9. Recommended as a spray pot mum.

The accompanying photographic drawing is a side view of a potted mum of Pink Papillon, with 4 cuttings in a 15 cm pot, with the colors being as nearly true as possible with illustrations of this type.

Of the commercial cultivars known to the inventor, the most similar in comparison to Pink Papillon is the parent cultivar Papillon. All traits of Pink Papillon are similar to those of Papillon, except for the ray floret color. The ray floret color of Pink Papillon is light pink (R.H.S. 69B to 75D), while the ray floret color of Papillon is described as red-purple (R.H.S. 71B to 71C).

The new cultivar can also be compared to sibling cultivar Bronze Papillon, also a spontaneous mutation and disclosed in pending Ser. No. 08/525,299, and sibling cultivar Cherry Papillon, an induced mutation of Papillon disclosed in U.S. Pat. No. P.P. 8,549. All siblings differ from each other and from the parent by ray floret color. Cherry Papillon further differs from its parent and from the other siblings by the relatively faster color fading of the ray florets.

In the following description color references are made to The Royal Horticultural Society Colour Chart. The color values were determined on plant material grown as a pinched spray pot mum in Salinas, Calif. on Jan. 30, 1995.
